Just enough js code to parse and run a simple Wasm file. Very naive and just using this to learn the spec. don't use in a real system. `wat2wasm test.wat && node wam.js ./test.wasm`
(module
(func
(export "add41")
(param $n i32)
(result i32)
i32.const 41
local.get $n
i32.add

0.5 -> 1.0 changes in extism
  • Port core of the runtime to wasm: Extism Kernel extism/extism#384
    • Extism is now a portable layer and we are no longer coupled to wasmtime!
  • New universal JS-SDK (browser, node, deno, & bun) https://github.com/extism/js-sdk
    • Universal library, no longer a separate node and a browser library
    • Uses native web platform Wasm support and threading (V8 in chrome, Deno, and Node; JSC in bun and Safari; and Spidermonkey in Firefox) instead of wasmtime
  • New Go-SDK https://github.com/extism/go-sdk
    • Switched out wasmtime with wazero thanks to the Extism kernel
    • Now no longer requires cgo and has a more idiomatic go API
  • Extism-CLI re-written in Go using new go-sdk https://github.com/extism/cli
  • Easier to install than python and installs as a single binary with no separate runtime object or python install
